Someone that I admire it is a British singer called Morrissey. I admire him because through his lyrics he talks about topics that not so many singers have the guts to do, such as politics, homosexuality and above all: animal rights.
On this last topic he has been engaged for so long and he has raised awareness among his fans, me included.
I admire that he's not afraid to speak his mind, even if that causes him problems like losing record deals or having the media speaking out against him.
